Hi, I am trying to build R 2.2.1 with Kazushige Goto's BLAS library (libgoto) and encountered a problem: I have two computers with the almost identical hardware (P4 Northwood CPU, i875 chipset, 2GB DDR400 RAM) and identical Linux OS. I have the latest version of libgoto for this CPU installed on both boxes (libgoto_northwood32p-r1.00.so) and I am using gcc compiler flags "-O2

I am looking at a data set containing two variables (x,y), each of which represents relative frequencies (rounded): data.frame(x = c(0.1,0.6,0.2,0.1), y = c(0.5,0.2,0.2,0.1)) x y 1 0.1 0.5 2 0.6 0.2 3 0.2 0.2 4 0.1 0.1 each of the rows reflects a "relation" between x and y, for example in row 4: 10% of the observations in x account for 10% of the observations in y. I

Some background: I have some data on structural dependencies in a base of code artifacts. The dependency structure is reflected in terms of relative node degrees, with each node representing some code unit (just as an example). This gives me real data of the following form (sorry for the longish posting): dat1 <- c(0.00245098039215686, 0, 0, 0, 0, 0, 0, 0, 0.0563725490196078, 0, 0, 0,

Hello, I am trying to install R0.99 on my PC running Solairis 7.

Hi all, I am currently trying to create a development environment including PostgreSQL 8.0.0rc1, R 2.0.1 and PL/R on a system running Fedora Cora 1. So far, I have suceeded in setting up PostgreSQL and R as a shared library - unfortunately I have not been able to link these two spheres by adding the PostgreSQL add-on PL/R due to some mysterious probs. I thoroughly followed the setup

Hi Martin, When I attended the LinuxWorld Expo in NYC back in January, I chatted with some folks at the AMD booth, as well as guys from Penguin Computing (where we bought our Opteron box). I was told that the Operton has this somewhat strange setup that the memory is controlled by one CPU. The net effect of this being that when both CPUs are running, one might only be running at around 90%

Hello, I'm having troubles while using the "Goto" function in a realtime extension. Here is the error message : -- Executing Goto("SIP/siemens1-081f56b0", "script_13_0|s|1") -- Goto (script_13_0,s,1) [Feb 7 13:24:21] WARNING[28666]: pbx.c:2455 __ast_pbx_run: Channel 'SIP/siemens1-081f56b0' sent into invalid extension 's' in context

FYI there is now serious talk of the Linux kernel dropping support for compilers that *don't* support asm goto.

Linux kernel is using the “asm goto” feature, other projects probably use it as well. I think it provides motivation to support it in LLVM. Regarding the complexity, I believe there is some infrastructure that we can at least partially reuse (the support for “indirectbr” instruction). My focus is adding “asm goto” support, the other things are indeed completely orthogonal and came up in bugs

Hi to all if someone of you is interested on it, i've changed the code of app_asr.c With these patch you can use the ASR application to play DTMF tones, so you can have your own AGI application that uses the ASR and manages the DTMF tones without change the dialplan.

Hi, i have been running R 2.11 compiles with the goto blas libraries successfully for about a year. I am running Ubuntu 10.10 64 bit. However, recently I have been periodically getting a segfault when running R (and numpy -- also compiled against goto blas). When I check the dmesg error log I get the following message R[28792]: segfault at 7f4183ed4000 ip 00007f4196f05f03 sp 00007f4192d55d20

Hello, guys. You know LLVM C backend emits 'goto' statement for branching, being based on the bytecode which is composed of units of the basic block. Therefore, I wonder if it would be hard to modify the C backend so as to spits out functions instead of 'goto' statements for branching. I'm just a novice so I have no good sense on this if this would be feasible. How do you

There is a paper from Andew Appel: http://portal.acm.org/citation.cfm?id=278285 it explains the connection between SSA basic blocks and functions pretty well. This paper may also help: http://www.jantar.org/papers/ssa-lambda/ Cheers, Gabor
